The Impact of American Petroleum Institute Certifications in Quality Management Systems: Analysis of API Spec Q1 and Q2 Certified Organizations

The present study aims to provide initial insight into the quality management system. More precisely, it describes whether and to what extent implementation of Quality Management System according to API Spec Q1 and/or Q2 can impact various companies in the oil and gas industry. A sample of international organizations is surveyed to understand how certifications affect organizational culture, passing through elements such as competitiveness, reputation, organizational performance, costs, and others. In addition to the certification itself, a rigorous and challenging process of implementation, review, restructuring is carried out, involving fundamental elements of the organization. During this stage, technical support becomes essential for a productive consolidation of the required requirements, and later, the improvement scenario is indispensable to maintain all the success factors in order to consolidate a quality management system within the organization. Thus, based on the findings, companies in the oil and gas segment may identify and reflect on the certification benefits to improve their approach to quality management systems, given the observations of managers and operational interviewees

The Barretos Cancer Hospital Animal Facility: implementation and results of a dedicated platform for preclinical oncology models

The Barretos Cancer Hospital Animal Facility (BCHAF) is a unique facility in Brazil exclusively dedicated to working with animal models for cancer research. In this article, we briefly present our modern facility and the main experiments performed, focusing on mutant strains of mice (PTCH-knockout and ApcMin mice), xenograft models, and patient-derived xenografts (PDXs). Our results show the progress and challenges in establishing these models and the need for having an appropriate representation of our cancer population to better understand tumor biology and to identify cancer biomarkers, which could be putatively targeted, allowing for personalized therapy.This study was funded by the Public Ministry of Labor Campinas (Research, Prevention and Education of Occupational Cancer) and by Pio XII Foundation, Barretos Cancer Hospital internal funds, Grant Number: 13/2021

Equidade de Acesso à Atenção Básica em Saúde Bucal

The objective of this study was to demonstrate face validity with a novel resource allocation framework designed to maximize equity into dental booking systems. The study was carried out in 2014. Eleven experts in primary dental care practice in Southern Brazil participated, using a three-round consensus group technique. First, the experts reached consensus on the items to be included in a 5-level diagnostic scale. They identified 21 clinical conditions and categorized them according to the oral health intervention required. Then, they described workload and activity standards for dental staff to carry out health promotion, oral disease prevention, dental treatment, dental rehabilitation, and urgent dental care. Finally, they agreed upon a set of wait times for primary dental care, establishing maximum waits from 2 to 365 days, according to the diagnostic classification. The framework demonstrated potential ability to promote more equitable access to primary dental services, since equal diagnostic classifications share the same waiting times for the dental care they requir

Inducible nitric oxide synthase (iNOS) expression in monocytes during acute Dengue Fever in patients and during in vitro infection

ABSTRACT: Mononuclear phagocytes are considered to be main targets for Dengue Virus (DENV) replication. These cells are activated after infection, producing proinflammatory mediators, including tumour-necrosis factor-α, which has also been detected in vivo. Nitric oxide (NO), usually produced by activated mononuclear phagocytes, has antimicrobial and antiviral activities. METHODS: The expression of DENV antigens and inducible nitric oxide synthase (iNOS) in human blood isolated monocytes were analysed by flow cytometry using cells either from patients with acute Dengue Fever or after DENV-1 in vitro infection. DENV-1 susceptibility to iNOS inhibition and NO production was investigated using N(G)-methyl L-Arginine (N(G)MLA) as an iNOS inhibitor, which was added to DENV-1 infected human monocytes, and sodium nitroprussiate (SNP), a NO donor, added to infected C6/36 mosquito cell clone. Viral antigens after treatments were detected by flow cytometry analysis. RESULTS: INOS expression in activated monocytes was observed in 10 out of 21 patients with Dengue Fever and was absent in cells from ten healthy individuals. DENV antigens detected in 25 out of 35 patients, were observed early during in vitro infection (3 days), significantly diminished with time, indicating that virus replicated, however monocytes controlled the infection. On the other hand, the iNOS expression was detected at increasing frequency in in vitro infected monocytes from three to six days, exhibiting an inverse relationship to DENV antigen expression. We demonstrated that the detection of the DENV-1 antigen was enhanced during monocyte treatment with N(G)MLA. In the mosquito cell line C6/36, virus detection was significantly reduced in the presence of SNP, when compared to that of untreated cells. CONCLUSION: This study is the first to reveal the activation of DENV infected monocytes based on induction of iNOS both in vivo and in vitro, as well as the susceptibility of DENV-1 to a NO production

Mucopolysaccharidosis I, II, and VI: Brief review and guidelines for treatment

Mucopolysaccharidoses (MPS) are rare genetic diseases caused by the deficiency of one of the lysosomal enzymes involved in the glycosaminoglycan (GAG) breakdown pathway. This metabolic block leads to the accumulation of GAG in various organs and tissues of the affected patients, resulting in a multisystemic clinical picture, sometimes including cognitive impairment. Until the beginning of the XXI century, treatment was mainly supportive. Bone marrow transplantation improved the natural course of the disease in some types of MPS, but the morbidity and mortality restricted its use to selected cases. The identification of the genes involved, the new molecular biology tools and the availability of animal models made it possible to develop specific enzyme replacement therapies (ERT) for these diseases. At present, a great number of Brazilian medical centers from all regions of the country have experience with ERT for MPS I, II, and VI, acquired not only through patient treatment but also in clinical trials. Taking the three types of MPS together, over 200 patients have been treated with ERT in our country. This document summarizes the experience of the professionals involved, along with the data available in the international literature, bringing together and harmonizing the information available on the management of these severe and progressive diseases, thus disclosing new prospects for Brazilian patients affected by these conditions
